Kufanele waziI-PTFE, ubaba we-fluoroplastics.Kodwayinii-PTFE enwetshiwe?Eyaziwa nangokuthi i-ePTFE, i-PTFE enwetshiwe inguqulo encane ye-PTFE.I-ePTFE ijabulela izici ezifanayo ne-PTFE. Lesi sihloko sizochaza umehluko phakathi kwazo kanye nezicelo zazo.
I-PTFE: ubaba we-fluoroplastics
Yini i-PTFE?
Njengoba api-olymer compound eyenziwe nge-tetrafluoroethylene nge-polymerization, i-PTFE inokuqina okuhle kwamakhemikhalifuthiukumelana nokugqwala,futhi uye wabaenye yezinto zokwakhange bestukugqwala resistance.I-PTFE ingakwaziukumelanacishe zonkeamakhemikhali,ngaphandleinsimbi encibilikisiwe ye-alkali, i-chlorine trifluoride, i-chlorine pentafluoride ne-chlorine ewuketshezi, kube njaloesetshenziswa kabanzi kuezihlukahlukeneizikhathito ukumelana ne-asidi ne-organic solvent.I-PTFE ngokwayo ayinabo ubuthi kubantu.
Izakhiwo ezihlukile ze-PTFE
I-PTFE iyi-fluoropolymer engavamile kakhulu futhi ibonisa ukusebenza okuhle kakhulu mayelana nezinga lokushisa, ukumelana namakhemikhali kanye nezakhiwo ezingezona izinduku.
● Okungabizi kakhulu;
● Cukusebenza okuqhubekayoat izinga lokushisa elingu-+260°C;
● LOw friction surface;
● Vukumelana nogesi okuphezulu.
Izicelo ze-PTFE
● NgokushoAbakhiqizi be-PTFE, i-PTFE inezinhlelo zokusebenza ezinkulu ezilandelayo.
●Eibekezelela ngisho nezimo ezinzima kakhulu futhi ilungele ukusetshenziswa ezinhlelweni eziningi.
●Iisivumelwano esisetshenziselwa ukukhiqiza ukudla neziphuzo,kuhlanganiseizinto zokupheka, ama-conveyor belt rollers, amakhava angaphezulu anganamathele, futhiI-temperature sensor casing.
●Pikakhulukazi ewusizo ekukhiqizweni kwemishini yangaphakathi neyangaphandle esindisa ukuphila.
●Pilungele ukufakwa kukagesi nokuvikela izingxenye ze-elekthronikhi.
● Yenzaimikhiqizo ehlukenein imboni yamakhemikhali,njengeama-gaskets,izintambo zomkhumbi namathangi amakhemikhali.
I-PTFE Enwetshiwe: i-microporous fluoropolymer
Yini i-PTFE enwetshiwe?
I-PTFE Enwetshiwe (i-ePTFE) iwuhlobo olusha lwe-polymer yezokwelapha, eyenziwe nge-polytetrafluoroethylene resin ngokwelula nezinye izindlela zokucubungula ezikhethekile.I-PTFE emhlophe, enwebekayo futhi eguquguqukayo enwetshiwe inokwakheka kwemeshi okwakhiwa ngoxhumo lwe-microfiber, futhi lawa ma-microfiber enza izimbotshana ezingenakubalwa, ukuze i-PTFE enwetshiwe igotshwe ngokuzenzakalelayo.Ukuhambisana kahle kwegazi layo kanye nokumelana nokuguga kwebhayoloji kuyayivumela ukuthi isetshenziswe ekwenzeni imithambo yegazi yokwenziwa, amabala enhliziyo neminye imikhiqizo yezokwelapha futhi ibe indawo engcono kakhulu yezicubu zebhayoloji.Ngokuvumelana okuhle kwe-biocompatibility kanye nesakhiwo esiyingqayizivele se-microporous, i-ePTFE ayinabo ubuthi, ayinawo umdlavuza, futhi ayiyona i-allergenic, futhi ngeke ikhiqize eminye imiphumela emibi.Amangqamuzana ezicubu zomuntu nemithambo yegazi angakhula abe ama-micro-pores abese enza ukuxhumana kwezicubu njengezicubu ezizimele.
Izakhiwo ezihlukile ze-PTFE enwetshiwe
I-PTFE enwetshiwe yabelana ngezici ezifanayo ku-PTFE.Impahla ayinabo ubuthi ngokuphelele futhi inenhlanzeko, futhi inikeza amazinga okushisa okusebenza afika ku-260°C.Ngaphezu kwalokho, i-ePTFE ijabulela okulandelayoizakhiwo.
● Ukumelana nekhemikhali ngamandla omugqa aphezulu;
● I-inert ngamakhemikhali;
● Amanzi angangeni ngaphansi kwengcindezi ephansi;
● I-dielectric engaguquki ephansi;
● Ukunwetshwa kwe-radial okuhle kakhulu nokumelana ne-UV.
Izicelo ze-ePTFE
1. Izifakelo zezokwelapha
I-ePTFE engasebenzi ngokuphelele ingasetshenziswa ezixazululweni ezihlukahlukene zokuvuselela, okuhlanganisa imithambo yegazi yokwenziwa kanye neziqephu zokuvuselelwa kwezicubu ezithambile kanye nokuhlinza okuhlinzayo kwemithambo, inhliziyo, okuvamile kanye nokuhlinzwa kwamathambo, ngaleyo ndlela kuzuzise kokubili odokotela neziguli.IImikhiqizo yezokwelapha ye-ePTFE iyakwazi ukusebenza ngokuhambisana nezicubu zomzimba futhi ibuyisele ukusebenza kwayo okuvamile.
2. I-Fluorofiber
Ei-PTFE enwetshiweimicubabeamandla aphezulu, ukuncipha okuphansi, ukumelana nemihuzuko, nokumelana ne-UV okwedlulele, kanjaloqinisekisaingukuzinza okuhle nobuqotho ezindaweni ezimbi kakhulu.Lokhucishe ukuthii-fiber inemisebenzi eminingi futhi ingalukwa, iphothwe, ilukwe noma ithungelwe ezinhlobonhlobo zezindwangu, okuhlanganisa ukupakishwa kokucindezela, intambo yokuthunga, izindwangu zokwakha kanye nefloss yamazinyo.
3. Gama-askets kanye ne-sealant
I-ePTFE inokumelana okuhle kakhulu kwamakhemikhali nokuhuzuka kanye nokumelana ngokwedlulele namazinga okushisa aphezulu naphansi, okuyenza ifaneleke kakhulu ukuthutha nokufaka uphawu.ofuketshezi lwezimboni.Ama-gaskets nemikhiqizo yokuvala kusukaSuko, okuhlanganisa isicaba, umugqa omncane kanye nama-sealant akhiwe ensimini, ayatholakala kuma-flange anoma yimuphi usayizi noma ukucaciswa.
